Comparison of Sheathless and Sheathed Guiding Catheters in Transradial Percutaneous Coronary Interventions: A Systematic Review and Meta-Analysis

Abstract

Conclusion: The sheathless TR approach showed lower rates of RAS and femoral conversion. Sheathless has a higher success rate; however, it also increased RAO. Thus, more trials are needed to confirm this technique’s long-term outcomes and complications.
